NAC — Cucumis melo

Summary

MELO3C023195.2, the melon NAC gene (symbol NAC, also known as ATAF, CmANAC2, CmNAC68, and others) on chromosome 12, encodes a NAC-domain transcription factor with DNA-binding transcription activator activity. It is associated with the regulation of root hair elongation, leaf senescence, photomorphogenesis, abscission, anther development, and responses to hypoxia and sucrose. The gene is linked to traits including fruit shape, carpel number, lignin content, ethylene sensitivity, photosynthetic rate, respiration rate, disease tolerance, and seedling growth. It has been connected to phenotypes such as oxidative stress response, carbon and nitrogen metabolism, abiotic stress tolerance, pathogen susceptibility, drought resistance, and thermomemory. Studies of related genes in other species link the family to drought tolerance, ABA sensitivity, salt stress sensitivity, and enhanced thermomemory.
